I advise that you drop out of MC. Even if she "finally acquiesced", it's not like there has been obvious signs that she wants to piece and she was the one who chose the counselor. MC would have been helpful during the time the marriage was degrading but it will go against you now. These days D lawyers actually advice the WAS to go into MC just to deliver the message (convince you through the counselor) or to buy time for the WAS's own purposes (wrap up that job, plan up post D life, etc). Imho its better use of your time to self-reflect and GAL. Only if you find a counselor who is pro marriage that you should do MC and even that only after you see positive changes in her that occurred organically.
Thanks, Peter. So, my IC suggested I ask W to go to MC for "clarity" even if it wasn't to be restorative. In hindsight, maybe a boneheaded move from someone who only meant well. Obviously, he isn't familiar with Divorcebusting. W agreed to let me pick the counselor, but I struck out with finding one who had availability. W got a tip on one from my stepdaughter's IC and I agreed. I will pull the plug after the initial session if it feels fruitless. I don't think W is going off the guidance of a D lawyer, but your point about delivering the message through the counselor is something to be leery of.
